System and method of determining real-time location and status of voice-over Wi-Fi (VoWiFi) users in heterogeneous network environment

Abstract

Embodiments of the present invention relate to systems and methods for restricting at least one service to a subscriber by receiving a connection request from a user equipment [102], wherein the connection request includes at least one of a UE identifier and a unique SIM identifier; generating one of a positive response and a negative response based on the connection request, wherein the positive response is generated in an event a user profile corresponding to the user equipment [102] is identified and the negative response is generated in an event the user profile corresponding to the user equipment [102] is not identified; and restricting the at least one service to the subscriber in an event, one of: the negative response is generated based on the connection request, a state information of a subscriber identity module (SIM) indicates detached, and a location area information of the SIM belongs to a forbidden list of areas.

What is claimed is: 
     
       1. A method of restricting at least one service to a subscriber based on a location area information, wherein the subscriber is associated with a unique Subscriber Identity Module (SIM) identifier of a subscriber identity module, the method comprising steps of:
 receiving a connection request from a user equipment (UE), wherein the connection request includes at least one of a UE identifier associated with the user equipment and the unique SIM identifier; 
 generating one of a positive response and a negative response based on the connection request, wherein the positive response is generated in an event a user profile corresponding to the user equipment is identified and the negative response is generated in an event the user profile corresponding to the user equipment is not identified, 
 the user profile comprises the unique SIM identifier, a state information and the location area information of the subscriber identity module, and 
 the state information indicates one of connected and detached, and 
 the location area information corresponds to a last location of the SIM in an event the subscriber is latched with a cellular network: and 
 restricting the at least one service to the subscriber in an event of: 
 the negative response is generated based on the connection request, 
 the state information of the subscriber identity module indicates detached, and 
 the location area information of the subscriber identity module belongs to a forbidden list of areas in which the at least one service is restricted to the subscriber. 
 
     
     
       2. The method as claimed in  claim 1 , wherein the at least one service comprises one of a voice-over Wi-Fi audio call, a voice-over Wi-Fi video call, a voice-over Wi-Fi message and a data-over Wi-Fi. 
     
     
       3. The method as claimed in  claim 1 , wherein the unique SIM identifier comprises one of an international mobile subscriber identifier, a mobile station international subscriber directory number and a unique mobile identification number. 
     
     
       4. The method as claimed in  claim 1 , wherein the UE identifier comprises one of an international user equipment identifier and a media access control address. 
     
     
       5. The method as claimed in  claim 1 , wherein the connected state information corresponds that the user equipment is latched to the cellular network. 
     
     
       6. The method as claimed in  claim 1 , wherein the detached state information corresponds that the user equipment is disconnected with the cellular network. 
     
     
       7. a system of restricting at least one service to a subscriber based on a location area information, wherein the subscriber is associated with a unique Subscriber Identity Module (SIM) identifier of a subscriber identity module, the system comprising:
 a first gateway configured to: 
 receive a connection request from a user equipment (UE), wherein the connection request includes at least one of a UE identifier associated with the user equipment and the unique SIM identifier; 
 an authentication server configured to: 
 receive the connection request from the first gateway, and generate one of a positive response and a negative response based on the connection request, wherein 
 the positive response is generated in an event a user profile corresponding to the user equipment is identified and the negative response is generated in an event the user profile corresponding to the user equipment is not identified, 
 the user profile comprises the unique SIM identifier, a state information of the subscriber identity module, the location area information corresponds to a last location of the SIM in an event the subscriber is latched with a cellular network, and 
 the state information indicates one of connected and detached; and 
 a decision engine configured to: 
 receive the location area information from a second gateway, and restrict the at least one service to the subscriber in an event of: 
 the negative response is generated based on the connection request, 
 state information of the subscriber identity module indicates detached, and 
 the location area information of the subscriber identity module belongs to a forbidden list of areas in which the at least one service is restricted to the subscriber. 
 
     
     
       8. The system as claimed in  claim 7 , wherein the at least one service comprises one of a voice-over Wi-Fi audio call, a voice-over Wi-Fi video call, a voice-over Wi-Fi message and a data-over Wi-Fi. 
     
     
       9. The system as claimed in  claim 7 , wherein the authentication server further configured to retrieve the user profile from a home server. 
     
     
       10. The system as claimed in  claim 7 , wherein the state information and the location area information are retrieved by the home server from a management entity in an event the home server receives a request from the authentication server. 
     
     
       11. The system as claimed in  claim 7 , wherein the first gateway and the user equipment are configured to communicate via at least one wireless access point.
